How to do a multifield validiation in Riena [message #722244]

I would like to use Riena ridgets in an existing RCP application and I wonder how to best do a client validation that involves several fields. For example suppose there are two date fields and it should be asserted that the second date is after the first.

Best regards,
Peter

I think the best way would be to write your own validator and pass the two ridget instances to the validator
constructor. Then add the one validator to each ridget. This way any time any of the two ridgets changes, the validator
can get to the two values and check that the range is ok.

what do you think ?

Hi Christian,

Thanks for the suggestion. I suppose it would work like that but was not yet able to do it. I have currently two problems with this:
1. If I edit for example the second date, how can I trigger a revalidation of the first? Calling ridget.revalidate() would do the trick but would also lead to a recursion if called on the wrong ridget. Or should I add markers to the widgets myself? In this case I probably should always return ok.
2. (This has probably nothing to do with the original question) The messages of my validator are never shown. The control is getting its red border but no message is visible.

Is there something wrong with this?
widgetVon = UIControlsFactory.createDatePickerComposite(parent);
delegate.addUIControl(widgetVon, "von");
...
IDateTextRidget ridgetVon = controller.getRidget("von");
ridgetVon.bindToModel(...);
ridgetVon.updateFromModel();
ridgetVon.setValidationRule(multFieldValidator, ValidationTime.ON_UPDATE_TO_MODEL);
tooltipMessageMarkerViewer.addRidget(ridgetVon);

Other ridgets like normal ITextRidget can display the validation messages with the same tooltipMessageMarkerViewer.

Regards,
Peter

Yes you would do a textRidget.setErrorMarker(true); (or false depending on what has happened) (or setErrorMarker(true,
"something is wrong here"); )

Looks like a bug to me. Please open a bug in Bugzilla...

Thanks, that helped. It works well now.
